And the equipment which needs to use two cameras to detect the body temperature is large in size, high in cost, inconvenient to carry in daily life and difficult to popularize for the public.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a camera head assembly according to an embodiment of the present invention, and as can be seen from fig. 1, a camera head assembly 10 provided by the present invention includes:
the image sensing layer 100, wherein a visible light acquisition region 101 and an infrared light acquisition region 102 are arranged on the photosensitive side of the image sensing layer 100;
the lens 200 is arranged in the light incidence direction of the image sensing layer 100;
the micro lens layer 300 is arranged between the image sensing layer 100 and the lens 200, an infrared cut-off area 301 and an infrared anti-reflection area 302 are arranged on one side, facing the lens 200, of the micro lens layer 300, and the infrared cut-off area 301 and the infrared anti-reflection area 302 respectively correspond to the visible light collection area 101 and the infrared light collection area 102 in the optical axis direction.
The purpose that this embodiment is in order to solve the unable detection body temperature of present camera, realizes body temperature detection through human infrared detection mode.
In the embodiment, the body temperature is detected by adjusting the structure of a CMOS (Complementary Metal Oxide Semiconductor) of the current camera in the digital image field, and changing the lens stacking mode without affecting the picture quality of the camera.
Because the CMOS sensor also responds to infrared light which cannot be seen by human eyes, the shot photo is reddish, and the processing chip cannot adjust the correct color. Therefore, when the lens is designed, an infrared cut-off filter is needed for filtering out infrared light and allowing colors observable by human eyes to penetrate.
Objects that are not absolutely zero radiate infrared light. The infrared body temperature measurement is body temperature data obtained by measuring infrared light radiated by a human body. The body temperature is also measured by detecting infrared light in this embodiment. However, as mentioned above, the structure of the lens is such that the light received by the CMOS does not have infrared light, and we need to think of a way to be compatible with two usage scenarios.
In the embodiment, the temperature measurement function is realized by adjusting some specific details on the basis of the overall structure of the lens. When the CMOS device takes a picture, in order to reduce the influence of infrared light on the picture quality, an infrared cut-off filter is required to be added, but when the body temperature is detected, infrared light energy is still required to irradiate the CMOS device. In order to satisfy the function of combining the two, the position of the infrared cut-off filter needs to be adjusted. The specific implementation mode is as follows:
on a CMOS device, one part is made into a Bayer array for color image recognition, and the other part is made into an IR array for infrared recognition by adding materials which are more sensitive to human infrared radiation, such as cadmium sulfide, thallium sulfide and lead sulfide, in a doping mode.
In this embodiment, the visible light collection area 101 includes a pixel array, and the infrared light collection area 102 includes an infrared array.
As shown in fig. 3, the left side is a bayer array, and the right side is an IR array sensitive to mid-and far-infrared bands. The IR array does not need to be many, and the body temperature is measured at a single point, so that theoretically one IR detection point is enough. However, in the present embodiment, the number of IR points is increased appropriately in order to improve the signal-to-noise ratio and the accuracy.
It should be noted that fig. 3 is only an embodiment in the present embodiment, and does not limit the array arrangement of the visible light collection area 101 and the infrared light collection area 102 in the image sensor 100. The array arrangement may also be uniform distribution of RGB and IR, or the IR may be located at one point of four corners and the center, and the rest positions are distributed over RGB, which is not limited in this embodiment.
In this embodiment, the infrared cut-off region 301 and the infrared anti-reflection region 302 are disposed on the microlens layer 300 in a film-coating manner.
It can be understood that an infrared antireflection film (i.e., serving as the infrared antireflection area 302) is coated on the microlens corresponding to the IR detection point in a film coating manner, so as to enhance the infrared light recognition efficiency, and meanwhile, the infrared cut filter is combined with the microlens array, i.e., a film (serving as the infrared cut area 301) for filtering out infrared light is produced on the microlens in a film coating manner. Thus, the infrared cut filter can be eliminated, and the thickness of the camera can be reduced.
In a typical lens structure, the ir-cut filter completely encloses the microlens array, but in this embodiment, the ir light is blocked. Therefore, in the above steps, the filter layer and the infrared antireflection film are only covered on the corresponding bayer array CMOS.
The present embodiment proposes a camera assembly 10, the camera assembly 10 including: the image sensing layer 100, wherein a visible light acquisition region 101 and an infrared light acquisition region 102 are arranged on the photosensitive side of the image sensing layer 100; the lens 200 is arranged in the light incidence direction of the image sensing layer 100; the micro lens layer 300 is arranged between the image sensing layer 100 and the lens 200, an infrared cut-off area 301 and an infrared anti-reflection area 302 are arranged on one side, facing the lens 200, of the micro lens layer 300, and the infrared cut-off area 301 and the infrared anti-reflection area 302 respectively correspond to the visible light collection area 101 and the infrared light collection area 102 in the optical axis direction.
